PLYMOUTH -- In 2005, drugs put David Kwist in prison. And on Wednesday, they played a big role in sending him right back. In a hearing in Marshall Superior Court, the 20-year-old Plymouth man admitted breaking a term of probation he received after he was caught assisting in the operation of a methamphetamine lab in 2004. According to court documents, police investigated a report of an exploding meth lab at a home in the 100 block of West Washington Street in Plymouth in December 2004. In the home, police reportedly found many of the materials used for making the drug, including drain cleaner, anhydrous ammonia and lithium batteries. Kwist, who lived in the residence at the time, was charged with four felony charges and one misdemeanor for his role in the operation. However, in April 2005, he struck a plea deal with prosecutors allowing him to plead guilty to a Class D felony of possessing anhydrous ammonia for use in a drug lab. He was sentenced on April 14, 2005, to serve a year and six months in prison, with six months of the sentence suspended. He was also ordered to serve a term of probation. However, after his release from prison, court records indicate he broke the terms of the plea deal on several occasions, including testing positive for marijuana use and engaging in criminal activity. After being arrested on several felony counts in Starke County, then pleading guilty to at least one of those counts, Kwist was formally charged in Marshall County with breaking the terms of his probation, according to court records. And on Wednesday, he reaped the fruits of his actions, when Marshall Superior Court Judge Robert Bowen revoked his probation and sent him to prison to serve the remaining six months of his original sentence. "Are you prepared to make an admittance that you violated those terms?" Bowen asked Kwist during the hearing. "Yes, I admit that," Kwist replied. Kwist received credit for the time he has served in the Marshall County Jail since April 20, when he was arrested on suspicion of violating his probation.
